I did my blue 93' STS at about 125,000. It is used daily for commute and pleasure trips, still holding fine at 168,000.

I also did my white 93' STS at 82,000, low use vechicle. At 98,000 still holding fine.

Nope, no time-serts or any other engine work for that matter.

172,000-miles and doing fine. WOT's almost every time its back on line.

Changed the coolant to Prestone 50/50 premix (mix with any color anti-freeze) and added the almighty "ginger root cookies" (Bars leak sealant pellets).

It hasn't owed me a thing for years.

When and how it finally does let go - it'll be long live the next Caddy :)


Add power to leave problems behind. Most braking is just - poor planning.

I think it will be obvious that most people will not have had their N* timeserted. It can be an expensive job and I'm sure a lot of cars would just end up in the junk yard or end up with a replacement engine.

I can't vote in this poll because I have the 4.9 engine. How about an option for the 4.9 engine in this poll? ;) (just kidding)


If you really want to make people safe drivers again then simply remove all the safety features from cars. No more seat belts, ABS brakes, traction control, air bags or stability control. No more anything. You'll see how quickly people will slow down and once again learn to drive like "normal" humans.

165K 97 STS - no idea

155K 96 Aurora - no idea

My best guess is that neither have had the operation

Well that's KIND of what I meant, but not really what I said. Maybe I should have titled the thread, "have you had thread problems on your Northstar"? I bet the vast majority, pre-Dexcool or not, have had no problems with their engines.

94' STS. ~69,500 miles. Never been time-serted.

All original except the battery and the PCM. Yes, I changed oil and filters (air and oil). Changed the coolant too.

1997 Deville Timerserted at 130K miles. Not back on the road yet, but the insert kit worked very well.

I think the head gasket was failing some time ago. Had a missing cylinder in the morning that would clear after a minute or so of idling. I think the deathblow on the gasket was when the water pump belt popped.

Hoping to squeeze at least 20K out of it before I let it go. :lol:

$3000-$4000 I believe, unless you do it yourself.

Both banks and some other odds and ends, I think the entire bill with tax was under $4500. Much much much less than swapping out the engine.

Interesting Poll Jadcock,

and while completely unscientific the results are a little surprising.

Based on your poll about 1/3 of us can expect to undergo this procedure :huh::lol::lol:

But seriously… I think another interesting poll would be

1) If your Northstar has been timeserted what year is/was it

-or-

2) How many miles were on your Northstar when it was timeserted

The reason I would ask #1 is it seems to me that when ever I see a post about timeserts lately it’s been a ’97 model. Perhaps a handful of bad head gaskets were used that year, or perhaps its just a matter of economics, maybe '97s are new enought to have enough value to justify the effort and cost.

Odd...

Yeah, like I said, the number here in particular will probably be abnormally high, because this is by nature a DIYer type place to be. Most of the people (read: millions) who never have problems won't come to a place like this. I can't wait to see how the results end up a few weeks from now after everyone has had a chance to input.

Can someone explain the process of timeserting ? And how do you do it yourself ?

28,000 miles. No timeserts. Just a water pump and two radio amps.

Did mine(94 Eldo/275) at 131k but not before several LimpHome Mode episodes...no harm done; cost about 3200 plus a 4 week car rental (long story) of 600. Good news is my mechanic knocked the car rental off his bill cuz they'd taken so long. Been running fine since (about 5k miles) except I had to do the trans solenoids for about 400...it's been a project car in many ways, but it sure is fun to drive

Jason,

Your assumption is correct ONLY if another assumption is accurate, which is ONLY people who never had problems won't come to a place like this. And I do not think this second assumption is accurate at all. Not ONLY the people who do not have problems won't come to this site but also millions who do have problems do not show up here. The bottom line is that we all regardless of our skills drive the same vehicles. If something happens to our vehicles it do happen to others as well and I am afraid the results of the poll you have initiated is quite accurate and representative (unfortunately).

One may want to drive a bulletproof (relatively) Honda or such a great car as N* equipped Cadillac but expect POSSIBLE costly problems with head gaskets down the road. Properly maintained cooling system was mentioned many times. Sure the better you maintain it the less is probability something will go bad, but looks like the problem may show up even in properly maintained vehicles.

Adallak, notice I said MOST people who never have problems won't come to a site like this. Certainly, there are people like you and me who still show up here, even though our cars are 100%. :)

I stand by my assessment (and posts in the archives agree) that a good percentage of folks who come here have at one point done so because of a problem, major or minor. Few come to actually brag about their car. If a third of all Northstars blow head gaskets, I guarantee Cadillac wouldn't have the sales it has today. Indeed, if my chances of getting a bad Northstar were 1 and 3, I wouldn't buy another one! But I know the real percentage is more like 1 in 100, or 1 in 1000. Without reliable data, it's impossible to make that assessment. Reliable data might include "how many times have dealerships across the country performed a Timesert repair?" 10,000x a year? I don't know. I know Cadillac builds Northstars by the hundreds of thousands each year, so that's in the 1-10% range.

Many members have said before that we can't base our perception of good or bad reliability from posts on an Internet forum, and I think that's absolutely true.
